Dr. Mahajan’s lab provides an immersive,  intensive training environment for students and fellows to discover the molecular mechanisms that cause blindness and develop therapies to prevent vision loss. Highly collaborative research teams are made up of scientists, surgeons, and engineers from around the world, interacting on a daily basis and using advanced scientific methods.

Postdoctoral Fellows

Young Joo Sun Ph.D.

Young Joo joined the Mahajan Lab in 2019. He received his bachelor’s degree in systems biology from the Yonsei University, Republic of Korea, in 2013 and completed his Ph.D. in biochemistry at the University of Iowa in 2019. Young Joo’s research interests are proteomics, structural biology, high-throughput screening, and protein-protein interaction engineering. He is currently working on structural biology of eye disease proteins.

Katherine Wert Ph.D.

Katie is currently a post-doctoral fellow. She earned a Master of Science in Human Clinical Nutrition from Columbia University in 2009 and a Ph.D. in Nutrition and Metabolic Biology from Columbia University in 2013. She completed a post-doctoral fellowship in genome engineering, stem cell, and developmental biology at the Whitehead Institute for Biomedical Research. Her overall research goal is to discover and understand the mechanisms underlying neuroretinal disease and to develop novel therapeutics for these complex degenerative disorders using gene therapy, cell transplantations, and genome engineering technologies. She utilizes gene editing strategies to create mouse models for human disease and studies specific mutations within human embryonic and induced pluripotent stem cells.
